Warframe Archimedea Personal Modifier Groups are a new weekly selection rule for Personal Modifiers in both Deep Archimedea and Temporal Archimedea. Digital Extremes revealed the system in Hotfix 44.0.1 after it was missed from the original Iceblade of Narin patch notes. Instead of drawing the weekly Personal Modifiers from one unrestricted pool, the game now separates them into four groups and selects one modifier from each group at reset.
The purpose is straightforward: stop a single week from stacking too many modifiers that attack the same part of a build. The first weekly roll using this structure is scheduled for September 28, 2026 at 00:00 UTC. Until that reset happens, the older weekly selection remains in place.
Warframe Archimedea Personal Modifier Groups: all four groups
The full Warframe Archimedea Personal Modifier Groups list contains 25 modifiers split across four pools. Group One is the largest and contains several broad combat penalties. Group Two is heavily focused on ability restrictions. Group Three targets ammunition, Gear, Companions and Transference. Group Four is built around survivability penalties such as shields, armor and healing.
| Group | Personal Modifiers |
|---|---|
| Group One | Ability Overload; Dropped Guard; Dull Blades; Framecurse Syndrome; Hypersensitive; Knifestep Syndrome; Low Yield; Secondary Wounds; Undersupplied |
| Group Two | Abbreviated Abilities; Channeled Greed; Constricted; Energy Exhaustion; Powerless; Shortened Reach |
| Group Three | Ammo Deficit; Gear Embargo; No Pets Allowed; Transference Distortion |
| Group Four | Anemic Shields; Fractured Armor; Infected Wounds; Lethargic Shields; Permanent Injury; Untreatable |
At each weekly reset, Warframe Archimedea Personal Modifier Groups contribute exactly one randomly selected modifier from Group One, one from Group Two, one from Group Three and one from Group Four. That gives the week a four-modifier set with deliberate category separation instead of four selections that can all come from the same style of penalty.
Why Digital Extremes added the four-group system
Digital Extremes said some Archimedea weeks could feel excessively punishing depending on the Personal Modifiers that appeared together. The grouping system is meant to reduce those extreme combinations without removing the challenge or making every week identical. It does not guarantee an easy set of modifiers, and a difficult roll can still happen, but the structure limits how heavily the weekly set can lean into one category.
That distinction matters when planning around Warframe Archimedea Personal Modifier Groups. You should still read all four active Personal Modifiers before choosing a loadout, but the weekly roll should now be more varied. For example, a week cannot fill all four Personal Modifier slots only with Group Two ability restrictions because the system can select only one entry from that group.
When do the new modifier groups go live?
The first Warframe Archimedea Personal Modifier Groups selection happens at the weekly reset on September 28, 2026 at 00:00 UTC. Iceblade of Narin launched on Wednesday, September 23, after that week’s Archimedea modifiers had already been selected. Hotfix 44.0.1 therefore documents the new system, but Digital Extremes says the first actual grouped roll waits for the next weekly reset.
For UK players, 00:00 UTC on September 28 falls at 1:00 AM BST. The important part is the server reset rather than your local calendar date. If you check Deep Archimedea before the reset, you may still see the old weekly selection. Check again after the weekly rollover before assuming the grouping system has failed to activate.
Do the groups change Deep Archimedea rewards?
Warframe Archimedea Personal Modifier Groups change how Personal Modifiers are generated, not the basic rule that optional parameters increase Research Points. Update 44 separately changed the Archimedea reward track and Warframe loadout parameter value. The maximum in one Elite Archimedea run is now 43 Research Points, the highest reward sits at 40 points, and the Legendary reward is at 37 points.
The Warframe Individual Parameter now awards three Research Points per mission instead of one. That is a separate Update 44 change, but it matters when deciding which restriction to leave behind. Digital Extremes specifically notes that the 40-point top reward can now be reached without one Individual Parameter other than the Warframe choice, while the Legendary reward can be reached while leaving two Individual Parameters behind.
Are Personal Modifier Groups the same as Loadout Parameters?
No. Warframe Archimedea Personal Modifier Groups only organise the Personal Modifiers that directly impose gameplay penalties. Loadout Parameters are the weekly Warframe and weapon choices shown above the Personal Modifiers. Update 44 also added Arsenal Boosts to matching loadout choices, but those boosts do not change which Personal Modifier is pulled from each group.
This is an important distinction when you open the Archimedea screen. Your four grouped Personal Modifiers are one layer of the difficulty setup. The listed Warframe, Primary, Secondary and Melee choices are another. You can evaluate them together when planning Research Points, but they are generated and applied as different systems.
What should you check after the September 28 reset?
After the reset, the easiest way to confirm Warframe Archimedea Personal Modifier Groups are active is to inspect the four Personal Modifiers shown in the Archimedea menu and compare each one with the group table above. You should have one modifier represented from each group. The exact four names are random, so there is no fixed September 28 combination to prepare for before the server actually rolls it.
- Check the weekly Personal Modifiers only after the September 28 00:00 UTC reset.
- Confirm that the four active modifiers come from four different groups.
- Do not confuse the grouped Personal Modifiers with the separate Warframe and weapon Loadout Parameters.
- Plan your Research Points around the actual weekly roll rather than a predicted combination.
What changed with the new Personal Modifiers in Update 44?
Alongside Warframe Archimedea Personal Modifier Groups, Update 44 added six Personal Modifiers to the wider rotation: Infected Wounds, Anemic Shields, Shortened Reach, No Pets Allowed, Channeled Greed and Low Yield. Framecurse Syndrome was also changed so activating an Ability now inflicts 50 damage and 150 shield damage. The group table in Hotfix 44.0.1 places those additions alongside the older modifiers, so they are part of the same weekly selection structure from the September 28 reset onward.
The practical takeaway is that Warframe Archimedea Personal Modifier Groups are a balancing rule, not a new toggle you need to unlock. Once the reset arrives, the game handles the four-group selection automatically. Your job is to inspect the result, choose which optional restrictions are worth the Research Points, and build around the four penalties that actually appeared that week.
Do the groups apply to Temporal Archimedea too?
Yes. Warframe Archimedea Personal Modifier Groups apply to Personal Modifier generation in both Deep Archimedea and Temporal Archimedea. The grouping rule is not exclusive to the Sanctum Anatomica version of the mode, even though many players will first notice it while checking Deep Archimedea after weekly reset.
You also do not need to opt into Warframe Archimedea Personal Modifier Groups from a settings menu. The selection happens automatically at reset. If you are comparing runs with friends, remember that the weekly set is generated by the system and is not a personal list that each player manually builds from the four pools.
For planning purposes, Warframe Archimedea Personal Modifier Groups are best treated as the framework around the four weekly penalties. The actual challenge still comes from the specific modifiers selected, your loadout parameters and the mission sequence that appears that week.
In short, Warframe Archimedea Personal Modifier Groups control the weekly spread. Warframe Archimedea Personal Modifier Groups do not change which missions appear or automatically change your loadout.
